IMPROVEMENT lN OVERFLOW AND DISCHARGE VALVES FOR WASH-BOWLS, TUBS,BATHS, &c.

Specification forming part of Letters Patent No. 196,928, dated November6, 1877; application filed July 23, 1877.

To all whom it may concern.-

Beit known that I, HENRY OGDEN, of the city and county of Providence,and State of Rhode Island, have invented new and useful Improvements inCombined Overflow and Discharge Valves; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the'accompanying drawings, forming part of thisspecitication.

This invention has reference to that kind of valves used in stationarywash-bowls, washtubs, bath, watercloset, and other basins, in which itis desirable that the water should not reach beyond a certain ixedheight, and' in which a hermetically-sealed trap shall prevent theentrance of sewer-gas while the contents may be readily discharged; andit consists in the peculiar arrangement of the several parts, as will bemore fully set forth hereinafter.

Figure lis a view of the improved valve, partly in view and partly insection. Fig. 2 is a horizontal section through the line A B,

showing the arrangement of the spline by which the valve can be keptsuspended during the time required to discharge the con- Fig. 3 is ahorizontal section through the line G D. Fig. 4' is a transverseAsection, showing, on reduced scale, the connection of the overflow-pipewith a wash-bowl and the line of water-overliow therein. l

In the drawings, c is the cylindrical case,

V connected with the tub or basin by the inlet b,

and provided with the outlet c, which outletpipe extends upward to thevalve-seat g. d is a cylindrical case, closed at top and open at thebottom. This case extends below the upper end of the discharge-pipe cand below the valve-seat.l vThe outer case is therefore at all timespartially iilled with liquid up to a level with the valve-seat g, andthe cylindrical case d extends into this liquid, and thus forms a trapto prevent the entrance of sewer-gas.

E is an extension of the discharge-pipe, open at both ends, and providedwith the elastic ring f, which forms, with the valve-seat g, the valve.

The discharge-pipe E is supported concentric within the closed cylinderd, and, when the valve is closed, forms the overflow, the

same being made of such length as will place the inletb at the lowest,level, so as to -discharge all the liquidl and the upper end of the Icase a, near the bottom, by which impurities .may be removed from thebottom-of the `case c without disconnecting thevalve.

To the upper end ofthe closed cylinder d the stem c' is secured, and tothe upper end of this the handle k. The stem i is provided with aspline, l, and the bush m, through which the stem i extends, with agroove. When, therefore, a large tub, or any kind of tub or bowl, is tobe emptied, the knob or handle is raised, thus raising the valve f,discharge or overflow E, and the cylinder d, allowing the liquid to flowover the valve-seat g. By turning the knob or handle k the spline willrest on the bush m, and the discharge valve will remain open, and asthecylinder d, closed on top, still extends below .the valve-seat, thevalve may remain open and still prevent the entrance of .sewer-gas.

The upper end of the case a is provided with ascrew-cap, n, which can beunscrewed, and theoverflow E and cylinder d removed for repairs orinspection.

When this valve is connected with any tub or basin the length of theoverflow-pipe E will regulate the amount of water that can be. placed inthe same, provided the valve-seat is just below the bottom of thevessel. The

valve must, therefore, be made of such length as will place the upperend of the overflowpipe E onV a level with the water-line desired, andthe valve-seat r/ below the bottom of the vessel.V

rllhe construction and operation of this valve areverysimple'.Itcanbeexaminedandcleaned readily and without detaching the same; itprevents the possibility of the liquid rising above the desired level;and in all positions forms an eiicient trap for the entrance of gas,itfbeing always closed by the most -eci'ent hydraulic seal.-

. Having thus described my invention, Iclailn 'as new and desire tosecure by Letters Patent y 1. The combination, with the ease a, providedWith the inlet b and outlet c, of the cylinder d, closed on top, theoveriow E, valveseat g, and elastic valve j', all arranged withreference to each other, substantially as and for the purpose described.

2. In combination with the outlet-pipe c, eX- tending upward to thevalve g f, the over- HENRY OGDEN.
